Hey M198,
It would seem that the only way you are going to find some peace here- and some piece of mind with this T-Net community, it to take your rock to a university or college or a well-season, well-respected authenticator. You don't know anyone here from Adam's house cat, so there's no reason for you to believe that a)there are quite a number of very wise, sometimes professional members here to help you and advise you b)that we actually do not have one another's backs (read past posts on effigies or any other item of questionable authenticity- like 'plummets' for example. So, please. I think we're all urging you to bring it to a show or a respected educational arena or authenticator so you understand what we're trying so hard to tell you. We're all in the same boat- most of us, anyway. There are a ton of things I see on hunts- nearly every time I go out, which I honestly have no clue about- and I'm nearly 100% sure they were/are SOMEthing, but I just don't know what. Over the years, I've found that I'm wrong (due to lack of education/enlightenment) about 70% of the time. On the flip side, I find that as time goes by, I find that SOME things I've picked up- and didn't know or understand, are in fact, real tools- or real Somethings. The key is, you have to have an open mind. No matter what. You have to except that there are things you don't know or understand yet. If you enter into a conversation with the answer already in mind, there is no conversation. And there is no room to learn or grow in your knowledge base. These folks are good folks. I think we'd all be really pleased (albeit amazed...)to find out we were wrong about this. We want to learn too, you see. So whatever you find out about that piece, please share. Either way, we're ALL learning then. Right? Happy hunting!
